Embodiment Construction

[0022]Referring now to the drawings, wherein like reference numerals refer to like parts throughout, there is seen in FIG. 1 a coaxial cable connector, designated generally by reference numeral 10, extending along a longitudinal axis X—X and having a coaxial cable interconnected thereto. Although not expressly illustrated in the drawings, it should be understood that the coaxial cable comprises a central conductor immediately surrounded by a layer of dielectric material of predetermined thickness, an outer conductor concentric with the central conductor and surrounding the dielectric material, and an outer layer of insulating material surrounding the exterior surface of the outer conductor.

[0023]Connector 10 generally comprises a conductive body 14 having an input end 16, an output end 18, and a cavity 20 defined therein. Body 14 includes an externally threaded portion 22 positioned at its input end 16 (it should be understood that connector 10 is illustrated as being a “male” UMTR ...

Abstract

An electrically conductive element for protecting electrical components positioned within a cable connector or cable terminator from high voltage surges includes a ring that is positioned in circumferentially surrounding relation to the input pin of the connector or terminator that carries the signal being transmitted by the coaxial cable. The ring includes at least one prong that extends radially inward therefrom which terminates in close but non-contacting relation to the input pin. When a high voltage surge of electricity is carried by the coaxial cable transmission line, a spark is formed in the gap between the prong and the cable connector or terminator. As a consequence, the high voltage surge is transferred to the surge protection element which in turn conducts the electricity to the grounded body of the connector or terminator.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of and claims priority from U.S. patent application Ser. No. 09 / 726,821 filed Nov. 30, 2000 now U.S. Pat. No. 6,683,773 and entitled HIGH VOLTAGE SURGE PROTECTION ELEMENT FOR USE WITH CATV COAXIAL CABLE CONNECTORS.BACKGROUND OF THE INVENTION[0002]The present invention relates generally to devices for interconnecting coaxial cable to CATV systems, and more particularly to surge protection devices that protect the integrity of electronic components positioned within interconnect devices from high voltage surges of electricity.[0003]In the CATV industry, cable television signals are traditionally transmitted by coaxial cable. As the cable is extended through a distribution network, several types of electrical devices, such as filters, traps, amplifiers, and the like, are used to enhance the signal and ensure signal integrity throughout the transmission. It is therefore necessary to prepare a coaxial cable f...
